THE heatwave shows no sign of letting up after the highest temperature of the year was recorded yesterday – with the mercury forecast to hit a scorching 91F (33C) by tomorrow.

Temperatures rocketed to 86.4F at Hawarden airport in Flintshire, north Wales, yesterday, breaking the record of 84.9F set in St James’s Park, London, on Monday.

Parts of the UK are currently hotter than Athens and on a par with Kuala Lumpur and Rio de Janeiro while the roasting temperatures are causing some roads to melt.

In England, the hottest spot yesterday was Rostherne, Cheshire, with a temperature of 86F. Aviemore recorded Scotland’s peak with 78F while Castlederg in County Tyrone was Northern Ireland’s high point, with 80F.

The glorious sunshine meant that beaches around Britain yesterday were packed, such as Bournemouth. Today is expected to be another hot day with plenty of sunshine, but it may be cooler around the coast.

A high of 91F is possible tomorrow, according to the Met Office – well above the 63F UK average for this time of year – and the fine, hot weather looks set to continue into July.

Forecaster Mark Foster said: “Generally, it looks like it will stay drier and warmer than average. “Long days, very still conditions and clear skies help June temperatures to get very intense. The sun in June is the highest it gets in the sky and heat can build up over successive days.”

If the temperatures continue to rise, the UK could be set for one of the hottest months ever recorded in the UK. However, it is not good news for hay fever sufferers who are already struggling in the heat. And the roasting temperatures have caused travel chaos too.

But a spokesman for the centre said: “Drinking water will always be available. Visitors can request this from reception.”

The scorching weather also turned a lake in Didcot, Oxfordshire, into “fish soup”.

The Environment Agency urged people to report lakes turning green after dead fish were seen on the surface.

Agency officers visiting the site yesterday said the heat had caused a rapid increase in algae in the lake, which then suffocated the fish – a phenomenon known as an “algal bloom”.

While the heatwave will continue to the weekend, particularly in the South and West, it will begin to get breezier on Saturday.

Rail passengers feeling the heat

THIS was the scene at Waterloo station in London today as commuters faced severe overcrowding on the hottest day of the year.

Thousands of passengers endured long delays after a mid-afternoon fire in a train’s undercarriage. Rail users face more delays today due to the hot weather, officials warned last night.

Network Rail has imposed speed restrictions across the country because the severe heat makes rails expand, which puts them at risk of buckling. A Network Rail statement said: “We would like to apologise to passengers for ongoing delays.”
